my mods are air foil CAI and UD pulleys i have around 400 to spend was thinking of going with ported stock runners and ported stock plenum from arkansas polishing don't want change my exhaust so any better bang for the buck thanks car is a 89 formula L98 tpi

 

stock ported runners and plenum, 1.6 RR's and 3.73's would wake it up a bit, that would put you over 400 though...400 isnt a whole lot to work with...what is your plan with the car? Just wanna give it a lil extra juice? or even the upgraded 3.27s if your car did not come with em
just found this on ebay http://cgi.ebay.com/ebaymotors/CAMAR...item19c847f99a do that and spend the rest on 1.6 RR's..that could possibly be the best bang for your buck, save up a lil more and put 3.73s in it, wouldnt be too bad of a street machine

 

greAT THANKS i checked the rpo codes and thought it said 342 for the gears i will have to double check
